to my Cargo.toml in the [dependencies] section but cargo gives me the following error when building:
An unknown error occurred
When running cargo build --verbose I get the error:
failed to parse registry's information for: wayland-client
I'm new to Rust and I don't really know what to do with this information. When I add the line
glium = "0.16.0"
to my Cargo.toml I get the same error. (0.16.0 seems to be the current version of glium according to crates.io)
When I change the version number to a random
glium = "1"
I'm getting the following error:
no matching package named `glium` found (required by `glium_test`)
location searched: registry https://github.com/rust-lang/crates.io-index
version required: ^1
versions found: 0.16.0, 0.15.0, 0.14.0, ...
(Which explicitly states version 0.16.0)
The dependency rand = "0.3" for example works fine.
Your cargo (and rustc too) are quite old. Almost a year! It seems that the 0.16 version of glium requires newer toolchain. You can try your look with older version, eg. glium = "0.14", but the best solution would be just to install the newest toolchain.
Those are the versions that shipped with Ubuntu 16.04. You'll have to install it yourself from rust-lang.org to get something newer.
failed to parse registry's information for: wayland-client
I believe it is this problem:
Particularly, looking at the raw registry index, I can see that wayland-client 0.6.0 has a dependency on "name":"wayland-sys","req":"^0.6.0-alpha", and it's the -alpha part that older cargo fails on. It doesn't even matter that this version is yanked from crates.io - it still tries to get parsed.
If you can't upgrade, maybe you could ask the Ubuntu packager for cargo to backport the semver and cargo fixes.
